broken marble statue

Hi, I have broken Marble (http://www.lightemprador.com) statue and (http://maplered.com) I am after some advice on fixing him. Hes a stand (http://maplered.com) ing figure with crossed ankles. When I got him he had had been snapped at the ankles and (http://maplered.com) repaired, but today when I tried to move him he broke right at the repaired spot. Can you advise me on how to repair him? Much thanks
